/* ** ** Swift/XRT hardness ratio for Mrk 421. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 60108.915257 0.000602 0.26622 0.02126 0.95192 0 21.94361 0.80480 7.57597 0.27785 5.84188 0.41448 2.01828 0.14319 60108.916432 0.000573 0.26953 0.02199 0.96970 0 22.06237 0.83020 7.60230 0.28601 5.94643 0.43040 2.04861 0.14826 60108.917702 0.000697 0.21275 0.01711 0.97510 0 22.76797 0.76295 7.81017 0.26170 4.84397 0.35415 1.66039 0.12138 60108.919007 0.000608 0.24008 0.01981 0.97619 0 22.56835 0.80814 7.83482 0.28051 5.41828 0.40275 1.87782 0.13961 60108.920243 0.000628 0.23308 0.01867 0.97696 0 23.03347 0.80264 7.98085 0.27810 5.36855 0.38722 1.86029 0.13419 60108.921904 0.001033 0.24288 0.01532 0.95355 0 22.40161 0.62342 7.80468 0.21722 5.44092 0.30794 1.89613 0.10732 60108.986481 0.000272 0.21636 0.01706 1.00000 0 21.61139 0.72458 19.58519 0.65664 4.67578 0.33373 4.23282 0.30212 60108.987025 0.000272 0.22030 0.01734 1.00000 0 21.11070 0.71459 19.27524 0.65237 4.65078 0.33041 4.24761 0.30176 60108.987554 0.000258 0.23965 0.01906 0.98876 0 20.79560 0.72898 18.87171 0.66147 4.98365 0.35574 4.52142 0.32272 60108.988072 0.000260 0.23695 0.01870 0.98889 0 20.94517 0.72659 19.04233 0.66059 4.96294 0.35176 4.50875 0.31951 60108.988654 0.000321 0.19350 0.01500 1.00000 0 20.75086 0.66012 18.63966 0.59293 4.01521 0.28393 3.60961 0.25524 60108.989230 0.000255 0.25039 0.02004 1.00000 0 20.04611 0.72499 18.05754 0.65300 5.01927 0.35826 4.52142 0.32272 60108.989771 0.000286 0.20720 0.01635 1.00000 0 21.12329 0.69366 19.33606 0.63493 4.37680 0.31394 4.00499 0.28721 60108.990352 0.000295 0.22509 0.01770 0.97059 0 19.85009 0.66953 17.89340 0.60347 4.46810 0.31742 4.03309 0.28652 60108.990905 0.000258 0.25010 0.01984 0.97753 0 20.21161 0.72068 18.44931 0.65788 5.05497 0.35827 4.61240 0.32685 60108.991446 0.000284 0.21180 0.01685 1.00000 0 21.03346 0.70300 19.07589 0.63759 4.45496 0.32169 4.03791 0.29155 60108.992010 0.000281 0.21942 0.01721 1.00000 0 20.86502 0.70131 18.97780 0.63780 4.57827 0.32436 4.16386 0.29496 60108.992545 0.000255 0.23750 0.01894 1.00000 0 20.86914 0.73548 19.03875 0.67101 4.95650 0.35451 4.52838 0.32391 60108.993263 0.000463 0.22601 0.01383 1.00000 0 20.71249 0.55467 18.75744 0.50226 4.68127 0.25764 4.23379 0.23303
